使用gdi+裁剪圆形图像

Image image(strPath);

RECT pos = GetPos();

RECT padding = GetPadding();

HRGN rgn = CreateEllipticRgn(pos.left,pos.top,pos.right,pos.bottom);

Region region(rgn);

Graphics graph(hDC);

SolidBrush greenBrush(Color(255,255,255,255)); ;

Rect rc2(pos.left,pos.top,pos.right-pos.left-2,pos.bottom-pos.top-2);

graph.SetClip(®ion,CombineModeReplace);

graph.DrawImage(&image,padding.left,padding.top);

Graphics graph1(hDC);

graph1.SetSmoothingMode(SmoothingModeHighQuality);

graph1.DrawEllipse(&Pen(Color::White,2),rc2);
